Honeybees and magnetoreception.
immune sera, polyclonal rabbit antibodies to human IL-1 f3, or anti-p20 ICE and protein A-agarose. After extensive washes, the adsorbed proteins were eluted by boiling the beads in SDS-PAGE sample buffer and analyzed by SDS-PAGE and autoradiography. 13. The ICE homologs and p35 were expressed in E coli under the control of the X pL promoter. ICH-1 (7) and CPP32o (8) contained a polyhistidine li...
متن کاملMagnetoreception System in Honeybees (Apis mellifera)
Honeybees (Apis mellifera) undergo iron biomineralization, providing the basis for magnetoreception. We showed earlier the presence of superparamagnetic magnetite in iron granules formed in honeybees, and subscribed to the notion that external magnetic fields may cause expansion or contraction of the superparamagnetic particles in an orientation-specific manner, relaying the signal via cytoskel...
متن کاملMagnetoreception
Few subjects in animal behavior have more exotic mystery than magnetic-field sensitivity. A force we cannot sense, generated by events no one completely understands, creates field lines that pass through our bodies without any evident effect on us or on them. It is an energy felt as much by migrating lobsters on the sea floor as by ocean-crossing birds thousands of meters overhead, transduced i...
متن کاملMagnetoreception in animals
mals can detect Earth’s magnetic field has traveled the path from ridicule to well-established fact in little more than one generation. Dozens of experiments have now shown that diverse animal species, ranging from bees to salamanders to sea turtles to birds, have internal compasses. Some species use their compasses to navigate entire oceans, others to find better mud just a few inches away. Ce...
متن کاملQuantum coherence and sensitivity of avian magnetoreception.
Migratory birds and other species have the ability to navigate by sensing the geomagnetic field. Recent experiments indicate that the essential process in the navigation takes place in the bird's eye and uses chemical reaction involving molecular ions with unpaired electron spins (radical pair). Sensing is achieved via geomagnetic-dependent dynamics of the spins of the unpaired electrons. Here ...
